Applied with the Ulf's R-by along with the [2/2] as 5.10 material, thanks!


There was a bunch of discussion on this patch series and I thought the
consensus was to not apply these patches and instead implement a custom
qcom specific API that does this instead.

The power domains which were targeted
to use the flags will be replaced by
custom qcom specific API. So let's not
pick up the patch series.
